Maduro's remarks Saturday are the latest in a series of accusations alleging plots to destabilize his government or assassinate him. He has made at least 11 such accusations since the beginning of his presidency, CNN en Español reported last week.

Maduro canceled his plans to travel to New York and attend the U.N. General Assembly last week because of what he said were plots to physically harm him there.

Gabriel Reyes, a Venezuela-based political analyst, told CNN en Español last week that there could be another motivation behind the accusations.

Both Chavez and former Cuban leader Fidel Castro often made such claims, he said.

"Maduro as a pupil of both of them cannot do anything other than using assassination as a sort of alternative distracting agenda," he said.
